HEMAN OSBORNE, OF NEW YORK, N. Y.

WINDOW-SASH FASTENER.

Specification of Letters Patent.

Patented Nov. 17', 1908.

Application filed March 25, 1907. Serial No. 364,224.

To all whom it may concern: Be it known that I, HEMAN OSBORNE, a citizen of the United States of America, and resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Window-Sash Fasteners, of which the following is a full, clear, and exact description. The object of this invention is to provide a fastening device for sashes which will be simple and inexpensive of construction, practicable of application for its locking operation on the window casing, susceptible of being operated to lock or release the sash or sashes only within the room,and positive and certain in its window locking action.

The invention consists in the combination and arrangement of parts and the construction of certain of the parts all substantially as hereinafter fully described and set forth in the claims.

The improved window fastening is illustrated in the accompanying drawings in which,

Figure 1 is a horizontal sectional view through a window casing at about the level of the meeting rail of the upper and lower sashes and through portions of the window fastenin device which is shown as fitted into the win ow casing. Fig. 2 is an elevation and partial vertical section as seen from the inner or concealed side of the window casing stile, or as looking beyond the plane inclicated byline 22, Fig. 1. Line 1-1, on Fig. 2 indicates where the parts in section in Fig. 1 are taken. Fig. 3 is a perspective view of a, portion of the window casing in which the locking devices for both sashes are fitted,the, sashes not being shown. Fig. 4 is a view of a corner portion of a sash showing a series of bolt engagement sockets therein.

Similar characters of reference indicate corresponding parts in all of the views.

In the drawings,A represents the window casing of which B is the stile, C the stop or vertical casing strip on the inner or room side, and a a are the grooves or slide ways for the inner and outer sashes D and E, said grooves being separated by the parting bead b.

F represents the supporting plate comprised 1n and constituting the frame of the locking device fitted withln the window casing and sunk within the walls of the vertical Said plate comprises a horizontal member 10 and upwardly and downwardly extending members 12 and 13 projecting from different portions of the length of the horizontal member 12 in parallelism and along the line of the sash grooves 64 -a,the window casing behind the removable parting bead being mortised and adapted for the reception of said supporting plate, and suitably open, as shown in Fig. 1 at m, behind such plate for the accommodation of the movable parts of thepresent device which are mounted on the inner or rear side of the support plate.

13 represents the four screws for fastening the plate comprising the double arms 12 and 13 thereof.

G and 11 represent a pair of levers intermediately fulcrumed for swinging movement in parallel horizontal planes at the rear side of the horizontal member 10 of the support plate, these levers being fulcrumed at 15 and 16 to ear pieces 17 formed as integral parts of the support plate. The arms of the said levers G and H which are extended towards the room side of the window casing have push-rods G and H pivotally or otherwise suitably connected therewith, said rods projecting through openings 19, 19 formed in said plate and also through the window casing strip or stop C; and, as shown, these holes 19 and the headed or button provided push rods which project therethrough advantageously have their locations closely together and one directly above the other, at points inwardly offset from the sash groove.

G and H represent another pair of levers fulcrumed respectively to ear pieces 20 and 21 at the rear sides of the downwardly and upwardly extended members 13 and 12 of the said support plate,these intermediately pivoted levers G and H being arranged at right angles to the aforenamed levers G and H and the lever G has the end of one arm thereof jointed to the proximate end of the lever G while the lever H has the end of one of its arms jointed to the end of the lever H which meets it at right angles.

G and H represent axially horizontal locking bolts with which the oppositely extended ends of the levers G and 11 have connections or engagements, these being guided and normally projecting outwardly through the aforesaid downwardly and outwardly extending support plate members 13 and 12, and beyond the walls of the sash guiding grooves at different heights; and these bolts are adapted to engage in any one of the several sockets y in the edges of the inner and outer sockets.

g and ]L represent springs, each reacting against a lever of each of a set of compound levers pertaining to a given locking bolt and operative to maintain the bolts normally in their sash locking positions and the push rods and the intervening compound lever connections correspondingly positioned.

As constructed by me, each vertical support plate member, right angularly extended from the horizontal portion 10, is made with a tubular integrally formed bolt guide m having a slot m through its side, for the entrance therethrough of the tongue like end of the adjacent bolt operating lever G or H such tongue like lever end entering a slot or bifurcation in the inner end of the locking bolt and being jointed thereto by a pivot, as shown at 0 in Fig. 2.

The supporting plate having the several lever supporting ear lugs and the tubular bolt guides may be produced as a metal stamping or as a light casting; and the sockets j in the vertical edges of the sash are preferably to be provided with tubular metallic bushlng In operation, as manifest, an inward movement imparted to the upper push rod H will impart through the compound lever connections a corresponding inward and sash unlocking movement to the locking bolt II for the upper sash, leaving such sash free to be opened as far or as slightly as may be desired, to be again locked by engagement of the locking bolt in whatever socket in the sash edge may become alined therewith; and the inward forcing of the lower push rod effects a like operation of the locking bolt for the other sash.

I claim 1. In a window fastener, a support, adapted to be set in a window casing within and adjacent the sash way or groove thereof, having a lever fulcrumed thereon, a pushrod connected to a member of said lever and adapted to project through an opening therefor in the casing to one side of the sash V groove, another lever fulcrumed on said support .and engaged with the first lever, a locking bolt with which the second lever is connected and normally projecting outwardly beyond the wall of the sash guiding groove, and adapted to engage in a socket therefor in the edge of a sash, and a spring for maintaining the parts with the bolt normally in its projected locking position.

2. In a window fastener a support plate, adapted to be transversely set in a window casing within and adjacent the sash grooves thereof, comprising a horizontal member, and upwardly and downwardly extended members projecting from different portions of the length of such horizontal member, a pair of levers intermediately fulcrumed for swinging movements in parallel planes on the rear side of said horizontal member, a pair of push-rods connected to a member of each of said levers, and adapted to project through openings therefor in the casing inwardly beyond the sash grooves, another pair of levers fulcrumed respectively at the rear sides of the said upwardly and downwardly extended members of said support plate, and arranged at right angles to, and each connected with, one of said first named levers, axially horizontal locking bolts with which the oppositely extended ends of said second levers are connected, and normally projecting outwardly beyond the walls of the sash guiding grooves at different heights in the length of said grooves and adapted to engage in sockets therefor in the edges of both sashes for a window, and springs for maintaining the parts with the bolts normally in their projected, sash-locking, positions.

Signed by me at Springfield, Mass, in presence of two subscribing witnesses.

HEMAN OSBORNE.
